Abstract (en)
[origin: GB2431610A] A power tool, particularly a hammer drill, comprising; a body 4; a drive mechanism located within the body; at least one handle 10 moveably mounted on the body 4 by at least one connection point 18, 32; 16, 34; a vibration dampening mechanism connected between the body 4 and the handle 10 which reduces the amount of vibration, generated by the operation of the drive mechanism, being transferred from the body 4 to the handle. The vibration dampening mechanism comprises a dampener 56, such as a spring; characterised in that the vibration dampening mechanism further comprises a restraining mechanism 52; 54. This restricts the direction of the movement of the handle 10 at the connection point 18, 32; 16, 34 where it mounts to the body to substantially the direction of the dominant vibration experienced by that connection point 18, 32; 16, 34. The restraining mechanism can comprise a pivotal lever or slide. The handle can be connected at two connection points, the movement of each one being restricted to that of the dominant vibration experienced at each connection.
